APK, APK Installations

Sometimes we come across a situation where we try to install an APK file on our Android device, but it shows an error message saying “App not installed.” This can be frustrating, especially when we need that particular app.

Don’t worry; there are some solutions to fix this issue. Let’s explore them one by one.

What is an APK File?

An APK file stands for Android Package Kit, and it’s the file format used by the Android operating system for the distribution and installation of mobile applications. It contains all the necessary files needed to run an application on an Android device.

Why Does “App Not Installed” Error Occur?

The “App not installed” error can occur due to various reasons, such as:

  • The app is already installed on your device.
  • The APK file is corrupt or incomplete.
  • Your device doesn’t have enough storage space.
  • Your device doesn’t meet the minimum requirements needed for the app.

Solutions to Fix “App Not Installed” Error

Here are some solutions that you can try if you encounter this error:

1. Clear Cache and Data of Google Play Store

Clearing cache and data of Google Play Store can help in fixing this issue in some cases. Follow these steps:

  1. Go to your device’s settings and select “Apps & notifications. “
  2. Find and select “Google Play Store.

  3. Select “Storage & cache. “
  4. Select “Clear cache” and then “Clear storage. “

2. Enable Unknown Sources

If you’re trying to install an app from a third-party source rather than the Google Play Store, you need to enable unknown sources. Follow these steps:

  1. Go to your device’s settings and select “Security.”
  2. Find and select “Unknown sources.”
  3. Toggle the switch to enable unknown sources.

3. Check the APK File

Make sure that the APK file you’re trying to install is not corrupt or incomplete. You can download it again from a trusted source and try installing it.

4. Free Up Storage Space

If your device doesn’t have enough storage space, you won’t be able to install any new apps. Try deleting some unnecessary files or apps to free up some space.

5. Check Minimum Requirements

Some apps require specific minimum requirements to run correctly. Make sure that your device meets those requirements before attempting to install the app.


The “App not installed” error can be frustrating, but there are ways to fix it. Try these solutions one by one until you find the one that works for you. If none of them work, consider reaching out to the app developer or seeking help from a technical expert.
